  • METHOD FOR TREATING MALARIA, METHOD FOR KILLING MALARIA PARASITE, AND USE OF THE METHODS
    Publication number: 20130296230
    Abstract: A method of the present invention for treating malaria includes the step of administering, to a human or an animal, a therapeutically effective amount of drug for suppressing calcium ion exit from an intracellular organelle of the malaria parasite to an outside of the intracellular organelle and/or calcium ion entry from an outside of a cell of the malaria parasite into the cell.

  • Method of producing partial peptide of enolase protein from
    Patent number: 7713926
    Abstract: The peptide production method of the present invention produces a peptide (SEQ ID NO: 1) of a protein from Plasmodium falciparum, which is effective as a malaria vaccine. The method produces the peptide of SEQ ID NO: 1 by linking the fragments (i) through (v) shown below: (v) Asn-Asn-Asp-Xaa (SEQ ID NO: 2); (iv) Asp-Phe-Lys-Thr-Pro (SEQ ID NO: 3); (iii) Asn-Lys-Thr-Tyr-Asp-Leu (SEQ ID NO: 4); (ii) Phe-Tyr-Asn-Ser-Glu (SEQ ID NO: 5); and (i) Xaa-Ala-Ser-Glu (SEQ ID NO: 6), where ‘Xaa’ in (i) and (v) represents zero or any arbitrary number of amino acid residues.
